Blue Sea Systems Mini OLED Ammeter, Blue

The Blue Sea Systems Mini OLED Ammeter packs real-time current monitoring into a compact body that mounts in the same common 1-1/8" hole used by countless other small gauges — a convenient upgrade path for any panel with a spare round cutout, without needing to enlarge or redrill an existing hole for a full-size meter.

Key features

• Monitors -100A to 100A DC, 0.1A resolution
• Bright, waterproof, daylight-readable OLED screen in blue, easy to see in bright sun or full darkness
• Includes a 100A shunt (PN 9230)
• Reverse polarity protected, mounts in a 1-1/8in hole
• Positive or negative side wiring — more flexible than many larger digital ammeters in the lineup

Unlike some of Blue Sea's larger digital meters that only work on the negative side of a circuit, this Mini Ammeter can be wired on either the positive or negative side, giving more flexibility for where it fits into an existing circuit design without extra adapters or correction hardware.

Its compact size makes it a good fit for smaller panels, tight console spaces, or anywhere a full-size digital meter's footprint simply won't work. Pair it with the matching Mini OLED Voltmeter for a complete compact monitoring setup in the same blue display color, matched for a clean, coordinated look on the same panel.

Because it wires the same way as any other current-sensing shunt-based meter, an experienced installer can typically add this display to an existing circuit without any major rewiring beyond inserting the included shunt at the right point in the circuit.
